The period is given by
T = 2 * pi * (r^3/(G*M))^0.5
where T is the period, r is the radius, G is the gravitational constant, M is the mass of the earth
convert 621 km to meters
look up the Gravitational constant and the mass of the earth in kg
plug in the numbers, and solve
The Hubble Space Telescope orbits Earth 621 km above Earth's surface. What is the period of the telescope's orbit? Give answer with 5 significant figures.
